CARDlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 229,808, dated July 13,1880.

V Application filed June 30, 1879.

To all whom it ma/y concern Be it known that -l, 'AIBIATHAR W. DEAN, ofTaunton, in the-county of Bristol and State of Massachusetts, haveinvented a certain new and useful Improvement in Gardin g-Machines; andI do hereby declare the following to be a full, clear, and exactdescription of the same, reference being bad to the accompanyingdrawing, forming part of this specification, in

1 which the figure is a perspective view of a portion of acarding-machine, showing the application of my improvements.

My invention relates to that class of carding-machines in which a seriesof cards or flats I 5 mounted upon radially-sliding rods are employed inconnection with a revolving carding-cylinder 5 and it consists in aseries of independent fibrous wipers secured to the guide byv means ofcap-pieces and surrounding the guide-rods supporting the independentcards or flats, whereby said rods are effectually wiped of dirt orforeign matter, as hereinafter more fully set forth, and pointed out inthe claim.

2 5 In the accompanying drawing, A represents the carding-cylinder; B,the independent cards or flats G, the radial arms or rods uponwhich theflats are mounted; D D, the guides for the rods; E, adjustable collarson the rods, 0 and F springs mounted upon the rods between the upperguides and the adjustable collars, and adapted to keep the flats inproper working position, and to retract when lifted for cleaning. I

Thus far described the machine does not differ materially from thoseheretofore used; but it is open 'to an important objection, which it isthe design of my invention to remedy.

In the practical working of the machine it is 40 found that the'constantback-and-forth movement of the rods causes the cotton or dirt and otherforeign substances which naturally collect upon them to be carried intothe guides, and in a short time clog up the latter, so as to cause therods to bind and interfere with the proper action of the cards orflats.The rods then have to be taken out and the guides separately cleaned,which operation requires considerable labor and inconvenience andnecessitates the stoppage of the machine. To ob- 5o viate this loss oftime and labor and yet keep the bearings or guides clean and in goodworking condition, I employ what I term wipers, composed of woolen,cotton, "or other textile fabric, or of leather, rubber, cork, or other5 5 elastic material. These wipers may be arranged upon the upper guidesmerely, or upon both upper and lower guides, as preferred.

In the drawing I have shown three different kinds of wipers-one, W,consisting of a piece of cork having an aperture forthe passage of therod of slightly smaller diameter than that of the rod and secured to theguide by means I of glue or, adhesive cement; another, W, consisting ofa fabric washer, preferably woolen, 6 surrounding the rod and held inplace by means of a cap-piece, w; and athird, W consisting of a piece offabric fitted around the rod and held by pivoted arms a, a.

The Wipers do not fit snug enough around the rods to cause them to bind,but merely exert a light elastic pressure, just sufficieut to remove theparticles that have accumulated.

By this simple arrangement the flats or cards are kept always in goodworking condition, and the machine does not require to be stopped forcleaning, as heretofore.

It will be seen that in my construction each rod may be removed orreplaced independent-1y of the others.

Heretofore in this class of carding-machines, in which a series ofindependent cards or flats mounted upon radially-sliding rods encircledby spiral springs is employed in connection with a carding cylinder, twoouter 85 curved and concentric guides for the rods have been used, withthe space between them filled with a bushing of wood; and 'I lay noclaim to such invention, in which the bushing is employed to formelongated bearings for 0 the rods in their reciprocations, and is notapplied to the outer side of the guide to act as a wiper, nor can thebushing for one sliding rod be removed without removing the bushing forall the sliding rods. 5

I claim as my invention The combination, with the frame of the cardbyeach wiper may be 5 e detached ing-machine having the curved guides D D,without removing the 0mm tantially as of the sliding rod 0, independentflats B, described, and for the purpose set forth.
